[kronolith] CalDAV REPORT/Multi-Status problem

[lst_hoe02 at kwsoft.de]

Hello,

we try to get a CRM Application to use the Horde/Kronolith calender  
with CalDAV. The CRM refuses to do something useful and throw a error  
about Multi-Status. On the wire we got something like this:

Client:

REPORT /rpc.php/calendars/lst_hoe/calendar:x4oABU6jTahP5FEW0nglG3A/  
HTTP/1.1\r\n

With this data

<?xml version="1.0"?>
<C:calendar-query xmlns:C="urn:ietf:params:xml:ns:caldav">
     <D:prop xmlns:D="DAV:">
         <D:getetag/>
         <C:calendar-data>
             <C:comp name="VCALENDAR"/>
         </C:calendar-data>
     </D:prop>
     <C:filter>
         <C:comp-filter name="VCALENDAR">
             <C:comp-filter name="VEVENT">
                 <C:time-range end="20140820T105557Z"  
start="20140218T200121Z"/>
                 <C:prop-filter name="STATUS">
                     <C:text-match caseless="yes"  
collation="i;ascii-casemap">TENTATIVE</C:text-match>
                 </C:prop-filter>
             </C:comp-filter>
         </C:comp-filter>
     </C:filter>
</C:calendar-query>


Server (Horde) response:

HTTP/1.1 207 Multi-Status\r\n

<?xml version="1.0" encoding="utf-8"?>
<d:multistatus xmlns:d="DAV:" xmlns:s="http://sabredav.org/ns"  
xmlns:cal="urn:ietf:params:xml:ns:caldav"  
xmlns:cs="http://calendarserver.org/ns/"  
xmlns:card="urn:ietf:params:xml:ns:carddav"/>


The client is confused with this and give up. Is it a client error to  
not first issue a PROPFIND like for example Thunderbird/Lightning does  
or what could be the problem?

Thanks for any help

Andreas
